' To all whom it may concern:

- Be it known' that I, Fnnmuok VERMIL LION, a citizen of the UnitedStates, residing ramic pictures can be printed by the use of could notbe printed in machines of this or correspondin view. x i I In theaccompanying drawings wherein is standards ar'e held rigidin otherthroii the and 4, as cearlylshown. l5.

nature because ofthe fact that certain requirements have to be compliedwith, which requirements difier materially in each case.

The particular object of this invention is to devise a machine wherein,as has been above described, negatives of difi'erent types can beprinted in the same -machine and from the same light. Y

-With the above and other oliiects in view my invention consists'in suchdetails of construction and in the arrangement and combination of artsas willbehereinafter more fully descri ed and specifically pointed outin the appended claims.

In describing my invention in detail, reference will behad to theaccompanying drawings wherein like characters denote like partsthroughoutthe sev eral views, in w 1ch:.

Figure 1 is a elevation thereof, Fig. 3 is a sectional view showing theparts inclevation, Fig. 4 is a sectional view taken on line A-A of Fig,2, and Fig. 5 is a detail illustrated the preferred form of my mventionthe numeral I'jdesignates the su porting structure fortheframe work of te machine, which; sup rting structure con sists of a'. plurality 0standards, WhlOh have connected with, clearly of cress'pie'ees 2..

By disposing be had from the lightsheld therein, as Wlll be obvious; For the, purpose of reflecting thelight. upwardly A movable partition 7 extends Specification of eamlatent. tent 10, 914, Application filed September a, 1 12. seriaimnamaand for 5 the purpose hereinafter set forth,-refiectors =11 and 12connection with glass plate '13 is are provided which hav shown. mountedabove posed in a slanting position, upon-which may be placed sue paperfor-softening'the light, when such treatment of a negative is required.

' For the purpose of supporting the nega-- the lights as shown and dis-I mats forvignetting and tistives, a plate glass 1 is supported uponarms 15 and has operating thereoverv spring pressed members 16, composedof two parts hin edly connected at 16', which are caras shown. Theplungers are hingedly secured to the frame work, as shown at 18, andareprovided with handles 19 whereby. they may be more easily handled. Coilsprings 20are interposed between the pieces 21 and the memers 16 wherebyengagement with glass plate 14, for the purpose hereinafter appearing. Ifind it advantageousto provlde an efficient means for securelygholdingthe plungers in the operative position shown in Fig. 3. This meanscomprises a the frame work of the machine and a pivoted pawl 23 carriedby-the handle of the plungers. The pawls are adapted to engage thebrackets as shown whereby the secure holding of the plungers' isefi'ected. Any suitable electric circuit may be connected with themachine for the purpose of furnishing ower to the. lights, and desire.it to be un' erstood that I am not limited to an specific formwhatsoever. 11 the operation of the machine the nega tives are disposedupon the plate 14 and the sensitized paper placed thereon; The plum:

ers are then moved in place and the lamps ihted automatically 0 thedevice shown'in Fig. 5. Plunger's 17 pressing downward on me' her 23,closes the sameare pressed into bracket 22 whichis carried through themedium the electric circuit'by making connection between members 23 and24, thus lighting the lamps.

It 'will be readily realized that the inachine which I have disclosed isvery simple in construction and it is thought that the advantages andnovel feature of the same will be readily appreciated from the foregoingdescription.

I desire/it to be understood that I may make slight changes in theconstruction and in the arrangement and combination of parts, providedsuch changes fall Within the scope of the subjoined claims.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a photographic. printing apparatus, a frame, a relatively longtransparent bed for supporting the negat ve and sensitized element orelements thereon, a plurality of pressure back devices adapted to closedown on and back the bed,' a light chamber below and coextensive withthe bed and having reflectors along the side portions curved upwardlytoward said bed lamps disposed be-- tween said reflectors and arrangedin angular relation with respect to the vertical and in staggered order,and a removable partition for dividing off a portion of said asdescribed. photographic printing apparatus, a transparent bed forsupporting chamber, substantiall .72. In a a frame,

the negatii e and sensitized element or ele upwardly toward said bed,and lamps disposed between said reflectors and arranged in angular.relation with respect to each other, substantially as described.
